Think about who is going to tour more. Is Robyn doing a full US tour? Matt & Kim have been playing nonstop all over the nation for a while now. I'm pretty sure they might come some place that is close to you.
In saying that, don't think I'm trying to convince you not to see Matt & Kim. They are a fucking blast.
Robyn is touring as an opener for Katy Perry.. I'm not sure she could support an arena tour on her own.. but probably a club tour.
Robyn's been doing her club tour since last year, She could never never sell out an arena tour not in the us at least. I think most of fans like close up smaller venues for her anyway. I would for Royksopp and her to do a joint tour
